Look at Lee's manual brake conversion for pictures. You will want to move the linkage the opposite direction though to reduce pedal travel.

Im really hoping to hear some feedback from those with the 25mm brake master cylinder installed.

The 25mm master will make your pedal feel much more firm. You need to get an adjustable proportioning valve though.
The E30 has a stepped master cyl with different piston diameters for front and rear. The 25mm master cylinder has 25mm in both front and rear.
If I remember correctly the regular E30 master is 22mm/19mm.-Nick

I noticed you retained your air pump. Is the motor BARed?
I kept everything stock s52 obd2 just for simplicity since i had an entire e36 to part out. Im over on the east coast, no bar stuff over here, yet anyhowsLast edited by E30stan; 10-10-2013, 09:20 PM.

It will bleed fine, but air will be trapped at the top of the caliper, away from the bleeder. Air compresses and gives a spongy pedal.Originally posted by codyep3I hope to Christ you have looks going for you, because you sure as fuck don't have any intelligence.

If your bleeder valves are pointed down it's because you have the calipers swapped left to right and right to left (probably already been stated previously).

Also a stock e36 m3 brake master cylinder pumps 25.4 mm of fluid to the front and 22-23 to the rear, the 750i e32 bmc pumps 25.4 front and rear.

Is there a reason why prefer them to be on the wrong sides?

Ill report back to you once i install the wilwood proportioning valve thats on the way.
Why not just run the e36m brake master?
Use known perfect parts (new) and install them correctly.
Please stay away from me any anyone I know and care about on public roads until you have a properly functioning brake system.
Some aftermarket prop valve won't help you here.

Has anyone told you that you come across as an arrogant person? I dont want this to turn into some gladiatorial event, but you replied very rudely while i merely stated the facts.
Have you ever ran recycled parts on a car?
Do you realize we are on opposite coasts?
Although everyones entitled to their own opinion, I'm curious to hear actual experience related to my particular scenario; combination of parts.
I dont care to read your response, but will be entertained if you take the bait:)

Your symptoms are (besides the Upside down calipers)
Bad master cylinder.
Seems you have been avoiding this advice all along and don't really wish the car fixed.
Nobody gives a rip about your feelings; there is an entire genre of music devoted to this; it's called EMO
